Not sure I understand exactly. We don’t know if the universe is Huge, or just how Huge it is. If Tegmark’s hypothesis is correct the only universes that exist may be ones that correspond to certain mathematical structures, and these structures may be ones with specific physical regularities that make Boltzmann brains extremely unlikely.
We don’t seem to notice any Boltzmann-brain-like activity, which may be evidence that they are very rare.
Here is relevant post. And if Tegmark’s hypothesis are true, than you don’t need Boltzmann brains. There are infinitely many continuations of subjective experience, as there are infinitely many universes which have same physical laws as our universe, but distinct initial conditions. For example there is universe with initial conditions identical to current state of our universe, but the color of your room’s wallpaper.
